Photoluminescent signage

Abstract

A non-powered photoluminescent sign includes a clear substrate and a message. The message is positioned on a surface of the clear substrate. The message is defined by at least one opaque portion. At least one of the at least one opaque portion is photoluminescent. The message is viewable with ambient light and without ambient light. Methods and other photoluminescent signs are also provided.

1 . An exit sign comprising:
 a clear substrate comprising a front surface and a rear surface; and   a first letter, a second letter, a third letter, and a fourth letter arranged relative one another to provide an EXIT message; wherein   with respect to each of the first letter, the second letter, the third letter, and the fourth letter:
 the letter comprises a reflective portion and a photoluminescent portion; 
 a face of the letter is defined through cooperation of the photoluminescent portion and the reflective portion; 
 the photoluminescent portion facilitates visibility and readability of the letter without ambient light; and 
 the reflective portion facilitates visibility and readability of the letter in ambient light; and 
   the exit sign is not connected to an electric power source.   
     
     
         2 . The exit sign of  claim 1 , wherein the clear substrate comprises a rigid sheet. 
     
     
         3 . The exit sign of  claim 2 , wherein the rigid sheet is formed from plastic. 
     
     
         4 . The exit sign of  claim 1 , wherein the reflective portion is colored red or green. 
     
     
         5 . The exit sign of  claim 1 , wherein portions of the clear substrate not covered with the letters facilitate visibility through the clear substrate in ambient light of environment of the exit sign. 
     
     
         6 . The exit sign of  claim 5 , wherein portions of the clear substrate not covered with the letters facilitate frontal visibility through the clear substrate in ambient light of environment rearward of the exit sign. 
     
     
         7 . The exit sign of  claim 1 , wherein the clear substrate has a height in the range of about 6 inches to about 14 inches and the EXIT message has a height of about 7 inches. 
     
     
         8 . The exit sign of  claim 7 , further comprising a mounting bracket, wherein:
 the mounting bracket defines a first set of apertures and a second set of apertures;   the first set of apertures is configured for receiving fasteners extending in a first direction to facilitate attachment of the clear substrate to the mounting bracket; and   the second set of apertures is configured for receiving fasteners extending in a second direction to facilitate attachment of the mounting bracket to a wall or ceiling structure.   
     
     
         9 . The exit sign of  claim 8 , wherein the first direction is transverse to the second direction. 
     
     
         10 . The exit sign of  claim 1 , further comprising a mounting bracket, wherein:
 the mounting bracket defines a first set of apertures and a second set of apertures;   the first set of apertures is configured for receiving fasteners extending in a first direction to facilitate attachment of the clear substrate to the mounting bracket; and   the second set of apertures is configured for receiving fasteners extending in a second direction to facilitate attachment of the mounting bracket to a wall or ceiling structure.   
     
     
         11 . The exit sign of  claim 10 , wherein the first direction is transverse to the second direction. 
     
     
         12 . A sign comprising:
 a substrate having a front surface and a rear surface;   a photoluminescent portion; and   a colored portion; wherein   the colored portion is larger than the photoluminescent portion such that the colored portion provides a border around a periphery of the photoluminescent portion;   at least one of the photoluminescent portion and the colored portion facilitates provision of a message; and   wherein the sign is not connected to an electric power source.   
     
     
         13 . The sign of  claim 12 , wherein a rear surface of the colored portion is adhered to the front surface of the substrate. 
     
     
         14 . The sign of  claim 13 , wherein a rear surface of the photoluminescent portion is adhered to a front surface of the colored portion. 
     
     
         15 . The sign of  claim 14 , wherein the colored portion is reflective. 
     
     
         16 . The sign of  claim 15 , further comprising:
 a mounting bracket, wherein:   the mounting bracket defines a first set of apertures and a second set of apertures;   the first set of apertures is configured for receiving fasteners extending in a first direction to facilitate attachment of the substrate to the mounting bracket; and   the second set of apertures is configured for receiving fasteners extending in a second direction to facilitate attachment of the mounting bracket to a wall or ceiling structure.   
     
     
         17 . The sign of  claim 12 , further comprising:
 a mounting bracket, wherein:   the mounting bracket defines a first set of apertures and a second set of apertures;   the first set of apertures is configured for receiving fasteners extending in a first direction to facilitate attachment of the substrate to the mounting bracket; and   the second set of apertures is configured for receiving fasteners extending in a second direction to facilitate attachment of the mounting bracket to a wall or ceiling structure.
